Zero point motion and direct/indirect bandgap crossover in layered transition-metal dichalcogenides
L. Ortenzi, L. Pietronero, E. Cappelluti
Two-dimensional transition-metal dichalcogendes (es. MoS, WS, MoSe, \ldots) are among the most promising materials for bandgap engineering. Widely studied in the…
Band structure and electron-phonon coupling in HS:a tight-binding model
Luciano Ortenzi, Emmanuele Cappelluti, Luciano Pietronero
We present a robust tight-binding description, based on the Slater-Koster formalism, of the band structure of HS in the {\em Im}{\em m} structure, stable in the range…
Electron-phonon superconductivity in PtP compounds: from weak to strong coupling
Alaska Subedi, Luciano Ortenzi, Lilia Boeri
We study the newly discovered Pt phosphides PtP (=Sr, Ca, La) [ T. Takayama et al. Phys. Rev. Lett. 108, 237001 (2012)] using first-principles calculations and Migdal-Eli…
Accounting for spin fluctuations beyond LSDA in the density functional theory
L. Ortenzi, I. I. Mazin, P. Blaha +1
We present a method to correct the magnetic properties of itinerant systems in local spin density approximation (LSDA) and we apply it to the ferromagnetic-paramagnetic transition…
Extended Drude model and role of interband transitions in the mid-infrared spectra of pnictides
L. Benfatto, E. Cappelluti, L. Ortenzi +1
We analyze the outcomes of an extended-Drude-model approach to the optical spectra of pnictides, where the multiband nature of the electronic excitations requires a careful analysi…
Fermi surface shrinking and interband coupling in iron-based pnictides
L. Ortenzi, E. Cappelluti, L. Benfatto +1
Recent measurements of Fermi surface with de Haas-van Alphen oscillations in LaFePO showed a shrinking of the Fermi pockets with respect to first-principle LDA calculations, sugges…
